l GUARD BRACKET FOIE ELCTRIC My? invention relates to guard brackets foi-welectric wiring, anckmore particularly to :brackets for"supportingl guard rails .orl

boards: in .proximity to trolley Wires.

Onefobject ofv my inventionlis to provide' Va, bracket ythat is readily applicable toy Wire.

supports `of variousst'yles and sizes.

Anothery object ofimy invention is to pro-- nuts.v i i vide a bracket that is readily -radjustableain directions vertically and horizontally. transverse to'a wire: orqtrolley conductor. ivitlr which it is associated;L

Stil'lanother objectof my inventionfis to "simplify and improve .generally the structure f and arrangementy ofl guard -lnacketsv Some of thel formswvhich myinvention may ltake areA shovnklin the'acoompanying-j drawing, wherein Figure 1 1s a sectional` -vievv of a supporting struct-ure showing my bracket in1plaee,'a`nd taken on theline 1 1' of Fig. 2; lTig.` 2f is al vieiv taken' on the 'line .ll-'ll' of Fig. '1;5Figs 3 is a modification of .the structure of 1,-;and Fig; l i's--fa j planrvieiv of the yoke device of Fig. 3.

liVhileV my invention :is applicable touse invarious other relations, l haveshoivn it ascmployed inv association vvithva trolleyvire 3 that is supported by `a clainpi 4 of` any I'Well-known form, Which is 'inturn sup-f ported by arhanger 5 that isfconnec-ted to a` timber 6, lplaced. against `a supporting sure..Y

face Y p The principal partsofthe bracketgconsist of tivo collar members vl8 and 9 that, supportV bars l0 and 11 respectively of angular form, to which are. connectedchannel members 12 and 13. These parts may be of sheet metal or other suitable material. A pair of links 14 are pivotally connected to the collar 8 and the adjacent end of the collar 9 .lies between these links, the collar 9 being provided Vwith a clamping bolt 14 that extends through the slots in the links lll and affording a means for adjustment of the collars longitudinally of the links, to enable the collars to be tightly fitted to hangers of various dimensions. At their other ends, the collars 8 and 9 are detachably connected by means of an eye-bolt 15 that is pivotally connected to the collar 8 and can therefore be swung into 'and out of position in a slot that is provided ,in the adjacent end of the collar9, a Wing nut 16 being provided.v to clamp the collars 8 and 9 securely-in yposition .uponthe hanger` .5.

rPhe.anglebars 10' and 11 arefslottedjat.. their vupper ends, so that they'gmay,beachf1 jjusted.` laterally of thelwire 3, the bars .10 andE 11 beingheldninadjusted position ;.by;

means of bolts 17 that extend'throughgthefcollars 8 anc 9 and are` provided with `evs'fingf barsl() and-1 1 bymenasof boltsl, a series.

of vertically-spaced holes being providedjin..

the ba-rs. and f .the yokes, so ...that-the fyokes;

can 4be adjusted to desired vertical,heights..,f

The `yokes 12 and.1'3 serveasvsupportsfor, guardy members, suchras .boards V19, lit being` understood. that these`r boardsfare` of suit-.1.. able leng'ths u and that v.they are, supported. at suitableintervals by ,mea-ns of. bracketsV asl-justdescribed. lheyokes` 12 and13.,areI pivotally supported .on theY bolts 1.8,fso/that.. they can sWiveltoJ allovwtheguardiboardss to follow a desired inclination,l depending upon the grades orA slopes presentavhere they are employed. v

Referring to Figs,` 3 and 4,1 show al-moditied` form of bracketfas employedinconnecfw tion with, anfexpansion `bolt structurev 2O` that.;v

may be supportedin thereof 2 1foffa 'minein l The' bracket structure.`v 1plate22-thatfeorresponds to they collar fmembers 8 andi y9 andis,slotted/td` the usual manner. includes y permitl it to bei slid. into,v position as r,shown in ligi, :the expansion bolt being.- set Ito, provide sufficient` `clearance beneath; the` surif` face, f of., the 5 mine roo,fg.or beingwunsereived; to provide such clearance. `The collar plate'` 22 supports angle platesl 10a and 11?-, that correspond tothe plates 10 and` 11 of Fig. 1,

and these plates in turn support yokes 12a and 13a. thebracket parts, except rfor the the corresponding members of Figs. .1 and 2.

Not only does the arrangement above deyplate 22j, being` `adjustable as in the case of v scribed permitof the convenient and` secure j application of the bracket to Wire hangers of various styles and sizes,`but the boards 19 may be conveniently` located at .various vvertical positions With respect to the trolley sine-elf no provision were made for latera rios' i adjustment of the guardboards, they would at someplaces lie so closeto the Wire as to interfere with the operation of ay trolley, and at other points Would be disposed so far away from the `Wire asfto afford inadequate protection.

I claim as my invention l. A guard bracket comprising a pair of collar members arranged to embrace a' hanger, meanskfor pivotallyhconnecting said member-sat one end for movement' about an axis perpendicular to the plane of the collar members, `means `for adjusting the point of pivotal connection, in a direction tangentially of the said inembers,'means for detachably connecting the other ends of said collar members, and a guard rrail support carried V by each of the collar members.

y2.,A guard j bracket comprising collar members arranged to embrace a hanger,

means forconnecting adjacent ends of said members at various points tangentially thereof, and means on said collars for supv porting guard rails, the said means being adjustable radially of the collar members. i

3. A guard bracket comprising collar membersr arranged to embrace a hanger,

. means for connecting adjacent ends of said members at lvarious points vtangentially thereof, and means on said collars for supporting guard rails, the said means being adjustable axially' of said collar members.

4. A' guard.'` bracket comprising collar members arranged to embrace a hanger,

means for connecting adjacent ends of said vmembers at various points Vtangentially thereof, and means on said collars for supporting guard rails, the said means being adjustable radially and axially of said collar members.

5. A n vguard bracket comprisng a collar device arranged to embrace a hanger, a pair of angular supports carried bysaid device and each having af verticall extension, and a guard rail support connected to each of said kvertical extensions, the saidyangular supportv and guard rail supports being adjustable relative to each other and relative to the collar device.
